    I had my first appointment with Dr. Cornell today. I was actually supposed to have my first…read moreappointment next week but I was in a lot of pain and extremely uncomfortable that Dr. Cornell and the office manager lady Kim went out of their way and accommodated me and brought me in today at last minute. They truly cared about me as a patient and as a person. I moved to Knoxville, TN about 2 months ago for work. I've been seeing my previous urologist in NJ for years for my urological issues. My urological issues are embarrassing to me and it is very difficult for me to find the right person I'm comfortable with for treatment. I couldn't find anyone in Knoxville that could help my specific issue and that I was comfortable with as well. I did some research and I found Dr. Cornell and saw he had lots of experience with my issue and offered the same kind of treatments as my previous doctor. At my appointment today I felt extremely comfortable with Dr. Cornell. I was surprisingly more comfortable with him than my previous urologist I've seen for years. He is very nice and listens well. He offers excellent advice. And his treatment was even better and more effective than my NJ urologist as well. I am doing so much better right now and I'm grateful. I have to drive 3 hours each way to see Dr. Cornell but it is worth it to me. He is now my official urologist and I will be seeing him regularly. I am extremely grateful and relieved that I found him. I highly recommend him to anyone looking for a urologist. Honestly I believe he is the best doctor and this is the best doctor office I've ever been to. Please check him out. He will help you. Thank you Dr. Cornell and Kim. - Christopher Neller

    I was referred to Dr. Cornell by my internist, and I'm so glad I was!…read more I saw Dr. Cornell as a new patient today, and he and his staff could not have been nicer or more efficient. Once I got there and gave his office manager my paperwork, I only had to wait long enough for her to photocopy my license and insurance and start a chart, which took no more than 10 minutes. I was taken back quickly, and waited no more than 10 minutes again to see Dr. Cornell himself. Dr. Cornell was EXTREMELY thorough, and looked over my past history, looking for anything that could help him piece together a picture of what was going on with me; which I really appreciated. He answered every question (even if I accidentally asked more than once), made sure I knew exactly what was going on, and took as much time as I needed to understand his conclusions, course of treatment, and the reasoning behind it. Dr. Cornell listened and made sure he understood exactly what I was saying before coming to any conclusions or making a diagnosis. It was so wonderful to have a doctor that really listened and spent time with me. I cannot say enough about my experience with Dr. Cornell today.

    This is the most poorly run doctor's office I've ever visited. It's hard to get in touch via…read morephone, the hold times are forever. I received a message to confirm an appointment, but there's no option to cancel, only to confirm. I have to dial the office to get it canceled, and there's a 20 minute wait to talk to a person, and then this person puts me on hold so they can call another person ??? The physicians are decent, everyone else is inept. I visited a PA who was dressed in a track suit and unfamiliar with my file, totally professional. There's a sign in front warning patients not to be rude to the staff. Instead of telling people not to complain, maybe they should show as much care for their patients as they do for their own staff.

We were over an hour past our appointment time today and they provided ZERO proactive transparency about the delays, nor did any employee say they were sorry for the delays. Others in the waiting room had been waiting 2+ hours past their appointment times. We asked for Dr. Garcia-Roig to come and speak to us about the delays. He did not do that. Ultimately, we took about 4 hours off work today for this appointment (which was only scheduled today because Georgia Urology asked us to move to this day to ACCOMMODATE THEM). We finally had to leave because we had waited too long and there was no end in sight. I hope we receive a direct phone call from Dr. Garcia-Roig to explain and apologize. We will be escalating this issue further. We will no longer be patients of this practice given that they showed zero care or sympathy for us.

    I had an extremely concerning experience with Advanced Urology in Marietta, Georgia, specifically…read morerelated to how they handle VA Community Care patients and billing. I was referred to this clinic through VA Community Care for a VA-authorized vasectomy. Shortly after being contacted to schedule, I was told I would need to pay a $250 booking fee out of pocket. As a veteran using authorized Community Care, this immediately raised concern. Only after I pushed back and involved VA Community Care did the clinic reverse that position and acknowledge that the booking fee should be billed to the VA, not the veteran. After the appointment was scheduled, I then received messaging from the clinic stating that the procedure would cost $149 if a post-vasectomy semen analysis kit was included, and $0 if it was excluded. I was repeatedly told by the clinic that this analysis kit is a retail product and that, due to how they operate, the cost is routinely passed to veterans. This directly conflicted with what VA Community Care confirmed in writing. VA Community Care explicitly stated that labs and pathology relevant to the referral are covered, including post-vasectomy semen analysis and post-vasectomy test kits, and instructed the clinic to bill Optum using CPT code 89321. VA also stated that if a veteran paid anything to the provider, those charges must be refunded. I have included screenshots documenting both the VA's written guidance and the clinic's messages quoting out-of-pocket costs. I personally spoke with the director of the clinic's benefits department, who stated that CPT code 89321 does not cover the vasectomy or the analysis kit and that the clinic cannot use that code to bill the kit internally. Despite VA's written clarification, I was told that if I wanted the required post-vasectomy analysis completed, I would need to arrange follow-up separately through the VA. After further confirmation with VA Community Care, I learned that the Atlanta VA does not even perform post-vasectomy semen analysis locally, meaning this proposed alternative was not viable and would have left me without proper follow-up or forced into paying out of pocket later. Because the clinic could not or would not provide VA-authorized care from start to finish, and attempted to shift the burden of their internal billing limitations onto me as the patient, I cancelled my appointment. Veterans should be aware that this clinic appears to accept VA Community Care referrals while disputing or declining covered components of care when they do not align with the clinic's internal billing model. I strongly recommend that any veteran considering this clinic obtain written confirmation in advance that all aspects of care, including required follow-up testing, will be completed and billed appropriately, with no out-of-pocket cost.

    Rude, combative staff. Management doesn't address simple behavioral issues w associates. Definitely…read morenot a place you want to trust to handle your life threatening conditions.

    I had a prostate surgery here on 07/15/26 at the request of my doctor, Dr. Wm. Nabors. Of course…read morelike most men we don't want anybody messing around in our gluteus maximus regions, but at Dr. Nabors's urging, I relented. The surgery went well. He took 12 samples of my prostate to test for cancer. The 1st 8 were tolerable, but for some reason the last 4 were progressively excruciating. 2 days later I feel about 90% normal and will take a short walk later today. I don't have the name of your staff, but I remember Maurice (and his "twin" born on the same day [Jan. 13], different year). Also the clerk who check me in and the young lady nurse who took my vitals and escorted me to my surgery room were very kind and helpful. As I arrived at the parking lot I also met a lady (Dr. Joan Hader) who personally escorted me (along with Maurice) to the proper Suite and told me to tell Dr. Nabors's that SHE is the #1 Urologist here. Well because she shares the first name as my dearly departed mother it's kind of hard for me to disagree. Let's just call it a tie. Finally, I would like to give you and your staff a gift. I'm a retired Professor of Law, Politics, Philosophy and History who attended law school at Harvard for one year back in 1988-89 with Barack Obama. Since I also early in my career taught in the public schools I know first hand that they are not teaching students critical thinking, so I created a blog containing hundreds of my essays on all subjects and links to my my 11 books @ www.EllisWashingtonReport.com. My son, Stone a graduate student in Public Policy & Administration @George Washington U, also writes for me under the title "Socrates Corner." Please share this cognitive info with children and students ages 8-108 and thanks again Dr. Nabors and to your entire team at Urology Specialists of Atlanta.

First, they will push whatever the local pharmaceutical rep is selling. Once you find out that's not covered by insurance, they'll send another prescription to the pharmacy. Then they'll take 2-3 weeks to send the authorization, during which time the pharmacy will drop your standing prescription. I have been to the pharmacy multiple times, called the Dr's office multiple times, spoken with my insurance multiple times, and still do not have my prescription after waiting for 2 months. They milk your insurance, push pharma rep preferred name brands (likely with kickbacks), and don't really care how long it takes to get your medication to you. I eventually gave up and will now have to start the process over with another urologist. Save yourself and headache and GO SOMEWHERE ELSE! Quite possibly the worst experience I have had with any medial office.

I have enjoyed each visit because of this amazing staff. Doctor Timothy McCullough listens closely and afterwards makes recommendations for all options available but more importantly that they are the best options for your problem and situation. He is very thorough in explaining how those options are done and how they may improve your condition. I've maybe made 2 other reviews in my lifetime but this one I definitely needed to make.
